How the Enphase IQ Microinverter for PowerXT®-R-AC Module WorksThe Solaria PowerXT®-R-AC Module maximizes energy production by using a sophisticated Maximum Power Point Tracking (MPPT) algorithm. Each Enphase Microinverter is individually connected to one PV module in your array. This configuration enables an individual MPPT to control each PV module, ensuring that maximum power available from each PV module is exported to the utility grid regardless of the performance of the other PV modules in the array. While an individual PV module in the array may be affected by shading, soiling, orientation, or PV module mismatch, each Enphase Microinverter ensures top performance for its associated PV module.

System MonitoringOnce you install the Enphase IQ Envoy and provide an internet connection through a broadband router or modem, the Enphase IQ Microinverters automatically begin reporting to Enlighten. Enlighten presents current and historical system performance trends and informs you of PV system status.

Optimal ReliabilityMicroinverter systems are inherently more reliable than traditional inverters. The distributed nature of a microinverter system ensures that there is no single point of system failure in the PV system. Enphase Microinverters are designed to operate at full power at ambient temperatures as high as 65º C (150º F).

Ease of DesignPV systems using Solaria PowerXT®-R-AC Modules are very simple to design and install. You will not need string calculations or cumbersome traditional inverters. Low voltage DC wires are pre-connected from the PV module directly to the co-located microinverter, eliminating the risk of personnel exposure to dangerously high DC voltage.



The microinverter housing is designed for outdoor installation and complies with the NEMA 250, type 6 environmental enclosure rating standard:

NEMA 6 rating definition: Indoor or outdoor use primarily to provide a degree of protection against hose-directed water, the entry of water during occasional temporary submersion at a limited depth, and damage from external ice formation.

The Enphase Q Cable is available with connector spacing options to accommodate installation of PV modules in portrait or landscape orientation. For Enphase Q Cable ordering information, see “Enphase Q Cable Planning and Ordering” on page 37.

Planning the RackingPlan the racking position with the Microinverter in mind. Ensure that the racking does not interfere with the microinverter and its connectors.

Grounding ConsiderationsThe Enphase Microinverter models listed in this guide do not require grounding electrode conductors (GEC), equipment grounding conductors (EGC), or grounded conductor (neutral). Your Authority Having Jurisdiction (AHJ) may require you to bond the mounting bracket to the racking. If so, use UL2703 hardware or star washers. Refer Module Installation: Step 10 for details. The microinverter itself has a Class II double-insulated rating, which includes ground fault protection (GFP).

Branch Circuit CapacityPlan your AC branch circuits to meet the following limits for maximum number of microinverters per branch when protected with a 20 amp (maximum) over current protection device (OCPD).

NOTE: * Limits may vary. Refer to local requirements to define the number of microinverters per branch in your area.

Utility Service RequirementsThe Enphase IQ Microinverter for ACM work with single-phase service. Measure AC line voltages at the electrical utility connection to confirm that it is within the ranges shown:

Planning for PowerXT®-R-AC Module Installation

MAXIMUM* IQ 7+ MICROS PER AC BRANCH CIRCUIT (240 VAC)

13

MAXIMUM* IQ 7+ MICROS PER AC BRANCH CIRCUIT (208 VAC)

11

240 VOLT AC, SINGLE PHASEL1 to L2 211 to 264 VAC

L1, L2 to ground 106 to 132 VAC

208 VOLT AC, SINGLE PHASEL1 to L2 183 to 229 VAC

L1, L2 to ground 106 to 132 VAC



Wire Lengths and Voltage RiseWhen planning the system, you must select the appropriate AC conductor size to minimize voltage rise. Select the correct wire size based on the distance from the beginning of the AC branch circuit to the breaker in the load center. Enphase recommends a voltage rise total of less than 2% for the sections from the AC branch circuit to the breaker in the load center.

Enphase provides guidance about choosing wire size and maximum conductor lengths in the Voltage Rise Technical Brief at enphase.com/support. Refer to this brief for voltage rise values in Enphase Q Cables and on how to calculate voltage rise in other wire sections of the system.

Standard guidelines for voltage rise on feeder and AC branch circuit conductors might not be sufficient for microinverter AC branch circuits that contain the maximum allowable microinverters. This is due to high inherent voltage rise on the AC branch circuit.

Best practice: Center-feed the branch circuit to minimize voltage rise in a fully-populated branch. This practice greatly reduces the voltage rise as compared with an end-fed branch. To center-feed a branch, divide the circuit into two sub-branch circuits protected by a single OCPD.

Lightning and Surge SuppressionEnphase Microinverters have integral surge protection greater than most traditional inverters. However, if the surge has sufficient energy, the protection built into the microinverter can be exceeded, and the equipment can be damaged. For this reason, Enphase recommends that you protect your system with a lightning and/or surge suppression device. In addition to having some level of surge suppression, it is also important to have insurance that protects against lightning and electrical surges. Enphase has tested the devices in the following tables.

B. Provide an AC connection back to the electricity network using equipment and practices as required by local jurisdictions.

Step 2: Position the Enphase Q CableA. Plan each cable segment to allow drop connectors on the Enphase Q Cable to align with each AC Module. Allow

extra length for slack, cable turns, and any obstructions.

B. Mark the approximate centers of each PV module on the PV racking.

C. Lay out the cabling loosely on the roof for the AC branch circuit. Make sure the cable is positioned in a way that allows you to connect it to the microinverter.

D. Cut each segment of cable to meet your planned needs.

WARNING: Do not install the modules in a way that creates continuous tension on the Q Cable.

E. Once the cables are laid out per steps C & D, secure the cable to the rails before installing the modules.

F. Connect the Q Cable.

Position the Q Cable along the edge of the module



Step 3: Connect to a Junction BoxA. Connect the Enphase Q Cable into the junction box.

B. Refer to the wiring diagrams on page 44 for more information. Wire colors are listed in the following table.

WIRE COLORS

L1 – Black

L2 – Red

Step 4: Terminate the Unused End of the CablePlace sealing caps on unused connectors and terminate the unused end of the Enphase Q Cable as follows.

A. Cover any unused connectors with Enphase Sealing Caps. Listen for a click as the connectors engage.

WARNING: Risk of electric shock. Risk of fire. Install sealing caps on all unused AC connectors as these connectors become live when the system is energized. Sealing caps are required for protection against moisture ingress.

NOTE: If you need to remove a sealing cap, you must use the Enphase Disconnect Tool. See “Remove and Replace a Microinverter” on page 35.

B. Remove 13 mm (½ inch) of the cable sheath from the conductors. Use the terminator loop to measure 13 mm.

C. Slide the hex nut onto the cable. There is a grommet inside of the hex nut that should remain in place.

Terminator Body 13mm



D. Insert the cable into the terminator body so that each of the two wires land on opposite sides of the internal separator.

E. Insert a screwdriver into the slot on the top of the terminator to hold it in place and torque the nut to 7 Nm.

F. Hold the terminator body stationary with the screwdriver and turn only the hex nut to prevent conductors from twisting out of the separator.

NOTE: Turn only the hex nut to prevent conductors from twisting out of the separator.

G. Attach the terminated cable end to the PV racking with a cable clip or tie wrap so that the cable and terminator do not touch the roof.

WARNING: The terminator cannot be re-used. If you unscrew the nut, you must discard the terminator

Internal View



Step 5: Prepare the AC ModulesA. Before installing the AC module, the microinverters must be lifted from the shipping position. On the ground,

turn the AC Module so that the microinverter faces you. Using both hands, lift the microinverter up. You will hear four clicks as the microinverter locks into the installation position. Ensure the four latches are locked, and the microinverter is not tilted.

NOTE: If you need to move the module, you can return the microinverter to the shipping position using the Enphase Disconnect Tool. Use the tool to depress the four locking mechanisms on each corner of the microinverter to return it to the shipping position.

B. Position the AC Modules as planned on the rail.

The Microinverter is in the shipping position.

The Microinverter is lifted and ready for installation.

Make sure the microinverter is not tilted.

Use this end of the Disconnect Tool to depress the locking mechanisms.



Step 6: Module MountingThe Solaria Corporation PowerXT® Warranty is contingent upon modules being mounted in accordance to the requirements described in this section.

6.1 Site ConsiderationsSolaria modules should be mounted in locations that meet the following requirements.

y Module should not be mounted in locations where it will be in direct contact with salt water or ammonia. y When choosing a site, avoid obstructions that could cast shadows on the modules as much as possible.

6.2 Mechanical Installa tionSolaria module mounting configurations must meet the following requirements:

Installation Requirements: y Do not remove or alter the module frame. Creating additional mounting holes may damage the module and reduce the strength of the frame.

y For roof mounting, the modules should be mounted over a fire-resistant covering rated for the application. y Clearance of 7 mm or more between modules is required to allow for thermal expansion of the frames. y Clearance of 100 mm or more is recommended between the modules and the rooftop or nearest surface. y Always keep the back surface of the module free from any foreign objects or structural elements which could come into contact with the module.

y Ensure that the modules are not subject to wind or snow loads in excess of the maximum permissible loads and are not subject to excessive forces due to thermal expansion of the support structure.

y Modules have been tested to Mechanical Loading Test requirements of UL1703. y The fire rating of this module is valid only when mounted in the manner specified in the mechanical mounting instructions.

y The module is considered to be in compliance with UL1703 only when the module is mounted in the manner specified by the mounting instructions.

y A module with exposed conductive parts is considered to be in compliance with UL1703 only when it is electrically grounded in accordance with the instructions presented in this document and the requirements of the National Electrical Code.



Mounting Requirements:Modules can be secured with bolts or clamps.

y Mounting Using Bolts at Mounting Slot Locations: � Use the four 7.0mm [0.28in] x 10.0mm [0.39in] “MOUNTING SLOTS” shown on the diagram below and on module drawing in section 8. Use M6 (1/4″-20) stainless steel bolts, with nuts, two washers, and a locking washer, tightened to a minimum torque of 13.6-16.3 N-m (10-12 ft-lb). �When bolts are used for mounting, maximum allowed loading is 5400Pa (front) and 3600Pa (rear). �Note, rails supporting the bolted connections should run perpendicular to the length of the module so as to not interfere with the AC unit (see diagram on next page)

y Mounting Using Clamps: �When using clamps, place clamps within the allowable clamping areas identified in the table and diagrams below. Follow clamp manufacturer’s recommended hardware and torque requirements for solar installations. Various clamp systems specifically designed for PV module mountings are available and compatible with Solaria PowerXT®. In the absence of manufacturer’s recommendations for clamp size, Solaria recommends minimum clamp size of 40mm (1.57”). �Maximum Allowed Loading:

y Mounting Using Rail-less Racking Systems: � Typical rail-less racking system layout is shown in the diagram below. � Attachments are to be made on the long side of the module with maximum attachment span of 48 inches and maximum cantilever of 17 inches. � Follow racking system manufacturer’s recommendations for coupling clamps at the module corners, torques, and bonding methods. � For rail-less systems, maximum allowed loading is 2400Pa (front) and 2400Pa (rear). � Clamps should be clear of the microinverter by at least 1 ½”.

6.3 Module Direction and Tilt Angle y Modules produce maximum energy when they are pointed directly to the Sun. Modules get maximum sunlight throughout the year if they face South in Northern Hemisphere and they face North in Southern Hemisphere.

6.4 Module Orientation y Modules can be mounted in either “portrait” or “landscape” orientation relative to the roof but the mounting rails must always run perpendicular to the long side of the module so as to not interfere with the AC unit.



Step 7: Use the Serial Number Labels to Create the Installation MapThe Enphase Installation Map is a diagram of the physical location of each module in your PV installation. Copy or use the blank map on page 42 to record module placement for the system or provide your own layout if you require a larger or more intricate installation map.

Each AC Module, Enphase Envoy, and Enphase Battery have a removable serial number label. Build the installation map by peeling the serial number labels from the modules and placing the labels on the map. You will also place the Enphase IQ Envoy (required) and IQ Battery (optional) serial numbers on the map after installation.

After you have created the installation map, use the Enphase Installer Toolkit mobile app to record serial numbers and configure the system.

For more information, refer to “Detect the Microinverters” in the help topics of the Installer Toolkit app.

A. Remove the label from each module before passing it up to the roof. Apply the label to the proper position on the installation map.

B. Peel the label from the IQ Envoy (and Enphase IQ Battery, if installed) and affix it to the installation map.

C. Always keep a copy of the installation map for your records.

Affix serial number labels

Label affixed to the side of the Microinverter Label affixed to the top of the PV module frame



Step 8: Connect the Microinverters as the AC Modules are InstalledA. Place the modules on the roof. Do not place the modules in such a way that places pressure on the microinverter.

Minimum distance from the top edge of the module to the rail should be about 12 inches.

B. As each module is installed, connect the Q Cable to the microinverter. Listen for a click as the connectors engage.

C. Do not allow the rail to press on the microinverter.

Step 9: Manage the CablingA. Use cable clips to attach the cable to the module frame. Leave no more than 1.8 m (six feet) between cable clips.

B. Dress any excess cabling in loops so that it does not contact the roof. Do not form loops smaller than 12 cm (4¾ “) in diameter.

WARNING: Tripping Hazard. Loose cables can become a tripping hazard. Dress the Enphase Q Cable to minimize this potential.

NOTE: Some modules do not include framing on their shortest side. Cable clips cannot attach to the frameless side for cable management. Plan to use the longer, framed side for cable management when this is the case.

Cable Clip



Step 10: Grounding y Before installing the solar system, contact local authorities to determine the necessary system hardware grounding requirements.

y The AC cable has no neutral conductor. For neutral grounding, refer to the diagram in section 9.0. y Module frames should be electrically connected to an earth ground for safety and protection from lightning in accordance to the National Electric Code (NEC).

y Solaria PowerXT® solar modules may be installed on a mounting system certified to UL 2703 with approval of the mounting system manufacturer.

y When using a mounting system, grounding of modules must be accomplished by the method prescribed by the mounting system manufacturer.

y Where common grounding hardware (nuts, bolts, star washers, split-ring lock washers, flat washers and the like) are used to attach the solar module to a listed grounding/bonding device, the attachment must be made in conformance with the grounding device manufacturer’s instructions.

� Common hardware items such as nuts, bolts, star washers, lock washers, and the like have not been evaluated for electrical conductivity or for use as grounding devices and should be used only for maintaining mechanical connections and holding electrical grounding devices in the proper position for electrical conductivity. Such devices, where supplied with the module and evaluated through the requirements in UL1703, may be used for grounding connections in accordance with the instructions provided with the module.

y Follow these instructions to ground the module.

� The module frame has four 4.5 mm grounding holes (‘A’) that are shown on the module drawing. Ground marks are located next to the grounding holes. Attach a 10 AWG (2.588 mm diameter) bare copper ground conductor to a grounding lay-in lug mounted at one of the four grounding holes on the module frame. Use a grounding lug with tin plating and stainless-steel hardware (#10-32 hex head screw at 4 mm diameter, flat washers, tooth lock washer and nut). � A #10 flat washer must be used between the screw head and the grounding lug to prevent damage to the tin plating on the lug. Insert a #10 flat washer between the grounding lug and the module frame. A #10 tooth lock washer must be inserted between the nut and the module frame to break the anodized layer of the frame. This mechanical bond between the tooth lock washer and the frame of the module will ensure a good electrical bonding path. � The #10-32 assembly attachment screw must be tightened between 20-25 inch-pound. A 10 AWG bare copper ground conductor must be attached to the ground lug using the stainless-steel set screw provided by the lug manufacturer. Tighten the set screw between 10-15 inch-pound to ensure a strong mechanical and electrical bond.

Step 12: Set Up and Activate Monitoring

Refer to the Enphase IQ Envoy Quick Install Guide to install the IQ Envoy and set up system monitoring and grid management functions. This guide leads you through the following:

y Connecting the Envoy y Detecting devices and scanning the installation map y Connecting to Enlighten y Registering the system y Building the virtual array

NOTE: When the utility requires a profile other than the default IEEE 1547 (for example grids managed by Hawaii Electric Industries [HEI] including HECO) you must select an appropriate grid profile for your installation. You can set the grid profile through Enlighten, during system registration, or through Installer Toolkit at any time. You must have an Enphase Envoy communications gateway to set or change the grid profile. For more information on setting or changing the grid profile, refer to the Enphase IQ Envoy Installation and Operation Manual at enphase.com/support.




Maintenance y Solaria modules are virtually maintenance free. Following simple maintenance steps will ensure reliable production electric power for the expected life of the product.

y Inspect electrical and mechanical connections for safety and corrosion once every year. y Under most weather conditions, normal rainfall is sufficient to keep the module glass surface clean.

�Modules that are mounted at a small tilt angle will not self-clean as easily as modules that are mounted at large tilt angles. If dirt build-up becomes excessive, clean glass surface with water and soft cloth. Do not use harsh cleaning materials.

y Cleaning the back surface of the module is not necessary for proper operation.

Troubleshooting Follow all the safety measures described throughout this manual. Qualified personnel can use the following troubleshooting steps if the PV system does not operate correctly.

WARNING: Risk of electric shock. Do not attempt to repair the Solaria® PowerXT®-R-AC Module; it contains no user-serviceable parts. If it fails, contact Enphase customer service to obtain an RMA (return merchandise authorization) number and start the replacement process.

Status LED Indications and Error ReportingThe following section describes LED indications.LED Operation

LED COLOR INDICATES

Flashing green Normal operation. AC grid function is normal there is communication with the Envoy.

Flashing orange The AC grid is normal but there is no communication with the Envoy.

Flashing red The AC grid is either not present or not within specification.

SOLID REDThere is an active “DC Resistance Low, Power Off” condition or “GFDI” fault. To reset, refer to “DC Resistance Low – Power Off Condition” below.

The status LED on each microinverter lights green about six seconds after DC power is applied. It remains lit solid for two minutes, followed by six green blinks. After that, red blinks indicate that no grid is present if the system is not yet energized.

Any short red blinks after DC power is first applied to the microinverter indicate a failure during microinverter startup.

DC Resistance Low – Power Off ConditionFor all IQ Microinverter for ACM models, a solid red status LED when DC power has been cycled indicates the microinverter has detected a DC Resistance Low – Power Off event. The LED will remain red and the fault will continue to be reported by the Envoy until the error has been cleared.

An insulation resistance (IR) sensor in the microinverter measures the resistance between the positive and negative PV inputs to ground. If either resistance drops below a threshold, the microinverter stops power production and raises this condition. This may indicate defective module insulation, defective wiring or connectors, moisture ingress, or a similar problem. Although the cause may be temporary, this microinverter condition persists until the sensor is manually reset.

An IQ Envoy is required to clear this condition. The condition clears on operator command unless its cause is still present.

If a microinverter registers a “DC Resistance Low - Power Off” condition, you can attempt to clear this condition. If the condition does not clear after you perform the following procedure, contact Enphase Energy customer support at enphase.com/en-us/support/contact.

There are two ways to send a clear message to the microinverter. Note that the condition will not clear after sensor reset if the cause of the failure is still present. If the condition persists, contact your installer.




Method 1: Clear this Error Using EnlightenA. Log in to Enlighten and access the system.

B. Click the Events tab. The next screen shows a current “DC Resistance Low - Power Off” condition for the system.

C. Click DC Resistance Low - Power Off.

D. Where “n” is the number of affected devices, click n devices (show details).

E. Click the serial number of the affected microinverter.

F. Click Reset DC Resistance Low - Power Off Sensor. The system displays, “A DC Resistance Low- Power Off reset task was issued on [date and time] for this microinverter and is still pending.”

Method 2: Use Installer Toolkit to Clear the ConditionFollow the instructions in the Enphase IQ Envoy Installation and Operation Manual at enphase.com/support to clear this condition.

Other FaultsAll other faults are reported to the Envoy. Refer to the Enphase IQ Envoy Installation and Operation Manual at enphase.com/support for troubleshooting procedures.





Troubleshoot an Inoperable MicroinverterTo troubleshoot an inoperable microinverter, follow the steps in the order shown.

WARNING: Risk of electric shock. Always de-energize the AC branch circuit before servicing. Never disconnect the DC connectors under load.

WARNING: The Enphase Microinverters are powered by DC power from the PV modules. Make sure you disconnect the DC connections and reconnect DC power and then watch for the solid green about six seconds after connection to DC power.

A. Make sure AC breakers and disconnects are closed.

B. Check the connection to the utility grid and verify that the utility voltage is within allowable ranges.

C. Verify that AC line voltages at all solar power circuit breakers at the load center and subpanels are within the ranges shown in the following table.

D. Verify that AC line voltage at the junction box for each AC branch circuit is within the ranges shown in the following table:

240 VOLT AC, SINGLE PHASE

L1 to L2 211 to 264 VAC

L1, L2 to ground 106 to 132 VAC208 VOLT AC, SINGLE PHASE

L1 to L2 183 to 229 VACL1, L2 to ground 106 to 132 VAC

E. Using an Enphase disconnect tool, disconnect the AC cable for the microinverter in question from the Enphase Q Cable.

F. Verify that utility power is present at the microinverter by measuring line to line and line to ground at the Enphase Q Cable connector.

G. Visually check that the AC branch circuit connections (Enphase Q Cable and AC connections) are properly seated. Reseat if necessary. Check also for damage, such as rodent damage.

H. Make sure that any upstream AC disconnects, as well as the dedicated circuit breakers for each AC branch circuit, are functioning properly and are closed.

I. Disconnect and re-connect the Enphase DC connectors. The status LED of each microinverter will light solid green a few seconds after connection to DC power and then blink green six times to indicate normal start-up operation about two minutes after connecting to DC power. The LED subsequently resumes normal operation if the grid is present. See page 32 for normal LED operation.

J. Attach an ammeter clamp to one conductor of the DC cables from the PV module to measure microinverter current. This will be under one amp if AC is disconnected.



K. Verify the PV module DC voltage is within the allowable range shown in “Specifications” on page 39 of this manual.

L. Following the steps in Remove and Replace a Microinverter, remove the PV panel from the roof, and swap out the microinverter with one from a known good, adjacent AC module. If after checking Enlighten periodically (this may take up to 30 minutes), the problem moves to the adjacent module, this indicates that the PV module isn’t functioning correctly. If it stays in place, the problem is with the original microinverter. Contact Enphase Customer Support for help in reading the microinverter data and for help in obtaining a replacement microinverter, if needed

M. Check the DC connections between the microinverter and the PV module. The connection may need to be tightened or reseated. If the connection is worn or damaged, it may need replacement.

N. Verify with your utility that line frequency is within range.

O. If the problem persists, contact Customer Support at enphase.com/en-us/support/contact.

Remove and Replace a MicroinverterIf problems remain after following the troubleshooting steps listed previously, contact Enphase at enphase.com/en-us/support/contact. If Enphase authorizes a replacement, follow the steps below. To ensure the microinverter is not disconnected from the PV modules under load, follow the disconnection steps in the order shown:

A. De-energize the AC branch circuit breaker.

B. Enphase AC connectors are tool-removable only. To disconnect the microinverter from the Enphase Q Cable, insert the disconnect tool and remove the connector.

C. Remove the AC Module from the roof per manufacturer instructions.

D. Once on the ground, disconnect the PV module DC connector from the microinverter using the Enphase disconnect tool.

E. Press each of the four clips to free the microinverter.

F. Snap new replacement microinverter into place.

G. Connect the PV Module DC connectors to the microinverter.

H. Scan the new serial number.

NOTE: The serial number of the replacement microinverter will different from the serial number on the AC Module frame.

I. Bring the AC Module back onto the roof or other mounting location.

J. Connect the AC Module AC connector and DC Connector to the Q Cable.

K. Energize the AC branch circuit breaker, and verify operation of the replacement microinverter by checking the Status LED on the connector side of the microinverter.






L. On the ground, use the Installer Toolkit mobile app to delete the old microinverter serial number from the Enphase IQ Envoy database. In Installer Toolkit, once connected to the Envoy:

a. Tap Micros > Manage.

b. Tap the checkbox to the right of the microinverter serial number that you replaced.

c. Tap to delete the microinverter from the Envoy-S database.

M. Add the new microinverter serial number to the Envoy database by initiating a device scan using one of the following methods:

a. Method 1: Initiate a scan using the Installer Toolkit mobile app

y In Installer Toolkit, once connected to the IQ Envoy, navigate to the Overview screen. y From the Overview screen, tap Detected > Start Device Scan to start a new 30-minute device scan. y If device scanning on the IQ Envoy is inhibited, the app displays Scan Inhibited. If you need to add more microinverters to the system when device scanning is inhibited on the IQ Envoy, you must use the Installer Toolkit scanning tool to provision them on the IQ Envoy, rather than using the IQ Envoy’s device scanning function to discover them. If this is not possible and you need to enable device scanning on the IQ Envoy, contact Enphase Customer Support at enphase.com/en-us/support/contact.

b. Method 2: Use an IQ Envoy

y Press the Device Scan button on the IQ Envoy. The IQ Envoy begins a 15-minute scan to identify all of the microinverters deployed at the site. The Microinverter Communications LED flashes green during the scan.

N. Log in to Enlighten to use Enlighten’s Array Builder to add the newly detected microinverter to the virtual array.

O. Ship the old microinverter to Enphase using the supplied return-shipping label.

Microinverter Communications LEDDevice Scan button




Enphase Q Cable Planning and OrderingThe Enphase Q Cable is a continuous length of 12 AWG, double insulated, outdoor-rated cable with integrated connectors for microinverters. These connectors are preinstalled along the Q Cable at intervals to accommodate varying PV module widths. The microinverters plug directly into the cable connectors.

The cabling is compatible with a variety of PV racking systems. For a list of approved PV racking systems, refer to the PV Racking Compatibility document on the Enphase website at enphase.com/support.

Connector Spacing OptionsQ Cable is available in three connector spacing options. The gap between connectors on the cable can be 1.3 meters, 2.0 meters, or 2.3 meters. The 1.3 meter spacing is best suited for connecting PV modules installed in portrait orientation, while the 2.0 meter and 2.3 meter spacing allows you to install 60-cell and 72-cell PV modules in landscape orientation, respectively.

Cabling OptionsOrdering options include:

CABLE MODEL CONNECTOR SPACING PV MODULE ORIENTATION CONNECTOR COUNT PER BOX

Q-12-10-240 1.3m (50”) Portrait 240

Q-12-17-240 2.0m (78”) Landscape (60-cell) 240

Q-12-20-200 2.3m (90”) Landscape (72-cell) 200

The Cabling System is flexible enough to adapt to almost any solar design. To determine the cable type you need, apply the following considerations:

y When mixing PV modules in both portrait and landscape orientation, you may need to transition between cable types. See the preceding table for available cable types.

y To transition between cable types, install a field wireable connector. y In situations where portrait modules are widely spaced, you may need to use landscape spaced cables for the portrait-oriented PV modules and create loops of excess cable, if needed.

WARNING: Do not form loops smaller than 12 cm (4.75”) in diameter.



Grid Interconnection DetailsBoth the Enphase IQ 7 and the IQ 7+ Microinverter are grid support interactive inverters. This type of inverter is also known as a Grid Support Utility Interactive Inverter (GSUII). The IQ 7 and IQ 7+ also comply with California Rule 21 - 2016 and Hawaii Rule 14H - 2017.

Grid ProfilesIQ 7 and IQ 7+ Microinverters have field-adjustable voltage and frequency trip points. Trip points are input voltage and frequency values that trigger the microinverters to shut down when the values are exceeded. If local regulations require adjustments to these trip points, or if the grid profile was not set up during registration, the installer can set up the system to use an alternate Grid Profile (set of trip points).

NOTE: Only an authorized installer, following the requirements of the local electrical utility, is allowed to make Grid Profile adjustments.

NOTE: Grid profile changes are applied only after a microinverter is detected.

In some regions and in some situations, microinverter trip points may be adjusted to account for high grid voltage or for local conditions.

Grid profile management tasks include:

y Set the grid profile for your region y View or verify current trip point settings y Generate a report for confirmation of site settings to the utility or other authority

To modify the grid profile or the parameters within the grid profile, installers must log in to their Enlighten account using their credentials.

The following tables show the parameter settings for the grid profiles available for North America:
